Ulmus japonica, Sarg. (U. campestris var. japonica, Rehd.). Tree, to 100 ft., with a broad head and often more or less pendulous branchlets: young branchlets densely pubescent and rough with minute tubercles, pale yellowish brown, sometimes developing corky ridges: lvs. obovate or elliptic, acuminate, oblique at the base, scabrous and hairy above, pubescent beneath with slight axillary tufts of hairs, 3-5 in. long; pairs of veins 12-16; petiole 1/6 – 1/4 in. long, densely pubescent: fls. nearly sessile, tetramerous: fr. obovate-oblong, about 3/4 in. long, gradually narrowed toward the base, with an open notch at the apex; seed touching the notch. Japan, Manchuria, Amurland. G.F. 6:327. S.T.S. 2:101. — Intro. into the Arnold Arboretum in 1895; it has proved perfectly hardy there, grows rapidly, and promises to become a valuable ornamental tree.

 '''''Ulmus davidiana''''' var. '''''japonica''''' <small>Rehder</small>, the '''Japanese Elm''', is one of the larger and more graceful Asiatic elms, endemic to much of continental north-east [[Asia]] and [[Japan]], where it is most commonly found growing in swamp forest on young alluvial soils.
-Size and shape are variable, ranging from short trees bearing densely-branched broad crowns to tall, single-stemmed trees with narrow crowns <ref name=Heybroek,a>Heybroek, H. M. (1981). The Japanese elm species and their value for the Dutch elm breeding program. ''Proceedings of the Dutch Elm Disease symposium and workshop''. October 5–9, 1981, Winnipeg, Manitoba. pp 78–90</ref>. The young shoots often bear corky wings, similar to those of the European [[Field Elm]] ''U. minor'', to which it is closely related. The leaves are generally [[leaf shape|obovate]], < 11&nbsp;cm long, and with a coarse upper surface. The [[perfect flower|perfect]], [[apetalous]] wind-pollinated flowers emerge in early spring, before the leaves. The [[Samara (fruit)|samara]], <15&nbsp;mm long, is obovate to orbicular, occasionally hairy over its entire surface but more often glabrous <ref name=Heybroek>Heybroek, H. M. (1981).
